Many netizens have seen a lot of projectors with hundreds of yuan on the Internet. At this time, there is a problem. What is the difference between a projector with hundred of yuan and a projector with thousands of yuan? First of all, we need to understand the characteristics and performance of these projectors.
1. Difference of projection technology
The most significant difference between a few hundred yuan projector and a few thousand yuan projector is the display technology. Most of the display technology used by a hundred yuan projector is the single-chip LCD display technology. The thousand yuan projector uses the DLP display technology, which is also the two technologies commonly used by projectors. First, understand the single-chip LCD display technology and DLP display technology.
Single chip LCD display technology: the principle is to remove the backlight part of the LCD panel, and then use the high-power backlight to irradiate the LCD panel through the condenser. Because the LCD panel is transparent, the picture will be irradiated, and the image will be made by hitting the screen through the front focus lens and lens. Its key component is LCD panel.
DLP display technology: that is, digital light processing, which first processes the image signal through digital processing, and then projects the light. Its core component is DLP display chip, which is the most advanced optical switch device in the world. It contains 2 million micro microscopes with regular arrangement and mutual articulation. When the DLP chip coordinates with the digital video or image signal, light source and projection lens, the microscope can project the full digital image to the screen or other surfaces.
The cost of single-chip LCD technology is relatively low. Many people with strong DIY production ability use this kind of display technology for self-made projectors. The relatively high cost is the LCD panel. The larger the LCD panel, the better the display quality effect.
2. System differences
In the introduction of several hundred yuan projector products, we often see a variety of product configurations, such as Standard Version, WiFi intelligent version, intelligent voice version, etc. Only standard edition is a few hundred yuan price, and WiFi smart edition and voice smart edition are all priced at thousand yuan level. The standard projector of several hundred yuan has no system, does not support the same screen of mobile phone, does not have Bluetooth, or even has no independent sound. Resources are all implemented through external connections.
Thousands of Yuan projectors are usually equipped with customized operating system, which can support network connection, wireless screen projection, and far-field voice function. They are more intelligent devices. There are also thousands of Yuan projectors without operating system, which are more traditional bulb projectors, most of which are 3LCD display technology.
Performance difference
The performance difference of 100 yuan projector is quite obvious. First of all, it is artificial correction in focusing and correction, all of which need manual operation. Compared with thousands of yuan projector, intelligence is far from enough. At present, the mainstream 1000 Yuan intelligent projector has been able to focus automatically by laser, and has completely got rid of manual in automatic correction. At the same time, the 2D to 3D functions supported by mainstream products like Dangbei can't be experienced in a projector of several hundred yuan.
Generally speaking, the difference between a projector of several hundred yuan and a projector of several thousand yuan is quite large. There are obvious differences in optical parameters, projection parameters and performance configuration. In fact, the price of a few hundred yuan projector is only seven or eight hundred when it is displayed, and the prices of products with high matching points selected in the details page are also thousands. A projector of several hundred yuan is just enough to be used, and there is certainly no level of a thousand yuan projector in terms of experience and effect.
